As the processing capabilities of hand held radio communications devices such as radiotelephones and/or personal digital assistants (PDAs) increase, more advanced applications for these devices are being made available. A Wireless Application Protocol (WAP) enabled radiotelephone and/or PDA, for example, may include an Internet browser providing mobile Internet access. Moreover, content available for wireless internet access is rapidly increasing with increasing wireless communications system bandwidths and with increasing numbers of internet enabled radiotelephones and PDAs being used. Accordingly, there continues to exist a need for improved data processing functionality in radio communications devices.
